The aim of this project is to characterise the interactions between various known plant proteinase inhibitors and the major digestive enzymes of insects by structural and dynamic studies and to utilise mutational studies to design new inhibitors that more effectively bind to target proteinases. The outcomes will be the knowledge to design specific inhibitors to give optimal inhibition of specific insect proteinases. This knowledge will lead to novel approaches to protect economically important crops, such as cotton, from insect pests in Australia - potentially saving tens of millions of dollars per annum in chemical pesticide use and enhancing crop production in Australia and internationally.Read moreRead less
Theoretical and computational approaches to accurately predict the structures of a unique family of circular and knotted proteins. The primary outcome will be a fundamental new knowledge on cyclotide structures and a new protein engineering method to design stabilised proteins. Because cyclotides have significantly higher stabilities than conventional proteins, they have a range of pharmaceutical and agricultural applications.

The primary outcome will be a fundamental new knowledge on cyclotide structures and a new protein engineering method to design stabilised proteins. Because cyclotides have significantly higher stabilities than conventional proteins, they have a range of pharmaceutical and agricultural applications. Both fields of use have the potential for very great economic and social benefits for Australia. From a pharmaceutical perspective our computing development will greatly facilitate the design of stabilised peptide-based drugs using the cyclotide framework. Such drugs have potential sales of several billion dollars per annum and the royalty returns from successful commercialisation of IP can be substantial.Read moreRead less

The aim is to establish a facility that will use a robotic NMR instrument to help in the characterisation of drug-protein interactions and in the discovery of new drugs or agrichemicals. The significance is that with the wealth of new information arising on protein sequences from genomics programs there is an urgent need to accelerate the rate of discovery of ligands that bind to these proteins. Such ligands may provide useful drug leads or help in defining the function of newly discovered proteins. The outcomes will be new knowledge on protein structure and function, and potentially, new bio-active molecules.Read moreRead less
STRUCTURAL CHARACTERIZATION OF ACTIVE CONSTITUENTS IN PLANT EXTRACTS WITH POTENTIAL FOR THE CONTROL OF OVINE LICE AND PARASITIC WORMS. The control of lice and parasitic worms are two of the major problems currently confronting the Australian sheep industry. Several plant extracts utilized in traditional medicine have shown a remarkable efficacy in the control of these pests in humans.

The control of lice and parasitic worms are two of the major problems currently confronting the Australian sheep industry. Several plant extracts utilized in traditional medicine have shown a remarkable efficacy in the control of these pests in humans. This project will investigate the sheep lousicidal and anthelmintic activity of a number of plants, and identify and chemically characterize the active constituents. This research will lead to the production of more environmentally friendly pest control methods and overcome problems of insecticidal resistance currently facing the industry.Read moreRead less
Tailoring nano-crystal suspensions for extended ion supply to hydrophobic and hydrophilic leaf surfaces. Nutrient deficiency undermines the potential of billions of people and many nations. The requirement is to rapidly increase micro-nutrient delivery to support intensive and fortified crop production.

Nutrient deficiency undermines the potential of billions of people and many nations. The requirement is to rapidly increase micro-nutrient delivery to support intensive and fortified crop production. This proposal seeks to develop a controlled ion release system through the use of tailored suspensions of nano-crystal nutrient materials for delivery to plants through the leaves. This will increase yields from arable land, reduce water requirements and fertiliser applications, fortifying foods for better nutrition leading to improved human health and wellbeing. It leverages and applies recent significant advances in surface science and nanotechnology to gain improved outcomes in agriculture.Read moreRead less

Bioinspired 2D nanocatalysts for inorganic nitrogen cycle. This project aims to develop novel catalysts for high-efficient nitrogen fixation by learning from the natural enzymes, which can convert nitrogen or nitrate into reactive ammonia at very mild conditions.

This project aims to develop novel catalysts for high-efficient nitrogen fixation by learning from the natural enzymes, which can convert nitrogen or nitrate into reactive ammonia at very mild conditions. It is expected that the enzyme-mimicking catalysts possessing the nitrogen active sites similar with the natural enzymes will allow the effective fixation of nitrogen from both the atmosphere and the nitrogen excessively fertilized environment into reusable ammonia. The outcomes of this project will provide a sustainable approach to solve the issues in current unbalanced inorganic nitrogen cycle in the world and contribute to a green artificial nitrogen cycle while with minimized environmental impact.Read moreRead less

The overall goal is to use innovative methods in chemistry, biochemistry and molecular biology to determine the structures and functions of several families of circular proteins that have exciting pharmaceutical and agricultural applications. These molecules differ from conventional proteins in that they have no ends: their termini are seamlessly joined, thereby making them exceptionally stable and resistant to enzyme digestion. The big question is ?How and why does Nature produce circular proteins?" Increasing our knowledge of why circular proteins have evolved will facilitate their applications in drug design and in the development of novel insecticides.Read moreRead less
Structural studies of plant disease resistance proteins. Plant cells have evolved a gene-for-gene disease resistance mechanism, involving an interaction of a plant-derived receptor with a specific pathogen-derived molecule. Currently, plant breeders are restricted to the resistance genes available in particular crop species or sexually compatible relatives. In the last few years, several plant disease resistance genes have been identified, providing a foundation for studying the molecular basis ....Structural studies of plant disease resistance proteins. Plant cells have evolved a gene-for-gene disease resistance mechanism, involving an interaction of a plant-derived receptor with a specific pathogen-derived molecule. Currently, plant breeders are restricted to the resistance genes available in particular crop species or sexually compatible relatives. In the last few years, several plant disease resistance genes have been identified, providing a foundation for studying the molecular basis of the resistance process. We propose to obtain three-dimensional structural information on representative R proteins and their ligand complexes. This will form the basis for modifying existing resistance genes to confer resistance to new diseases, resulting in large economic benefits.Read moreRead less
